PARENT, OF HARTFORD, CONNECTICUT, ASSIGNOR T0 THE WHITLOCK COIL TIPE COMPANY, OF WEST HARTFORD, CONNECTICUT, .A CORPORATION OF CONNECTI- 'CUT HEAT IEXCHAN GER Application filed June 16,

rlhis invention relates generally to apparatus wherein an exchange of heat is eliected trom one duid to another by passing one ot the Huids through a plurality of tubes, about the tubes. As an instance of a use to which the present invention may be applied, heat exchangers of the sort for recovering heat from wastel process water may be referred to, such exchangers having a plurality of tubes positioned or suspended within the chamber of a tank or pit, the clean water to be heated being passed through the tubes and the Waste water, the heat of which is to be recovered, being passed about the tubes. While my improvements hnd peculiar application in a heat exchanger ot this sort, they are not limited thereto.

The invention relates, more particularly, to means for supporting the tubes having various features of novelty and advantage.

'llhe aim of the invention is to provide an improved arrangement for supporting the permit of a substantially unobstructed flow of water about the tubes and through the tank in which the tubes are located; which will not result in the rapid accumulation of dirt and foreign matteriin the exchanger, and which will allow the heat eX- changer to be easily and quickly cleaned when necessary.

it. turther aim of the invention is to provide tube supporting means which is very simplein construction, which may be economically manufactured, which will permit of ready and quick assembly, and which will support the tubes in proper relation.

@ther objects will be in part obvious and in part pointed out more in detail hereinutter.

"lhe invention accordingly consists in the ltfeatures of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set tor-th and the scope of the application of which will be indicated in the appended claims.

ln the accompanying drawings, wherein I have shown, for illustrative purposes, two embodiments which the present invention may take:

1928. Serial N0. 286,004.

Figure 1 is a view showing, more or less diagrammatically, a heat exchanger in cross section and in which the improvements of the present invention are incorporated;

Fig. 2 is a sectional view through a vertical series of tube` supports showing the manner in which the tubes are held;

Fig. 3 is a side View of a series of supports;

Fig. l is a perspective view of one of the clamps shown in Figs. l, 2 and 3;

Fig. 5 is a View similar to Fig. 2, but showing another embodiment;

Fig. 6 is a side elevational view of what is shown in Fig. 5; and

Fig. 7 is a perspective view of one of the clamps shown in Figs. 5 and 6.

Referring to the drawings in detail, and particularly to Figs. 1 to 4, A designates a chamber which may be in the form of a pit, the walls of which are shown by broken lines. The letter B designates one of the hangers resting upon the tops of the walls of the pit. Secured to the hanger' is a top strap C which supports depending tie rods D carrying, at their lower ends, a bottom strap E. The letter P designates the pipes.

In the present illustrative disclosures, the pipes or tubes P extend horizontally and are arranged in rows lying in vertical planes.

The pipes of adjacent rows are supported by clamping members or elements arranged in pairs which are spaced vertically by sleeve portions. The clamping elements of each pair are preferably of identical construction and are in opposed or inverted relation relative to one another so that each pair of clamping elements will embrace a. pair of pipes. In the embodiment shown in Figs. 1 to 4, the sleeve portions are integral with the clamping elements or portions, while in the embodiment shown in Figs. 5, 6 and 7 the sleeve portions are separate elements, as hereinafter explained more in detail. Referring to the embodiment shown in Figs. 1 to 4, the clamping elements are designated generally by the numeral 10 and the sleeve portions by the numeral 11. Each clamping portion has, at each end, a curved arm 12 forming aparti or semi-cylindrical seat or pocket 13. Extending through the central portion of each clamping element is an opening for accommodating a tie rod D. In this embodiment, the sleeve-like or spacing portion 11 is formed integral with the clamping element and has an opening which is a continuation of the opening 15. The clamping elements are strung or threaded on the tie rod D in pairs, the clamping elements of each pair being in opposed or inverted relation to one another so that the curved arms 12 will embrace a pair of tubes P. The pairs of clamping elements are held in spaced apart relation by interposed sleeve or spacing portions 11. The tie rods are suspended from and connected to the upper strap C by nuts 20. The clamping elements are held on the tie rod by a nut 21. The lower strap E may be secured to the tie rod by nuts 22.

In the embodiment shown in Figs. 5 to 7, the clamping elements 10 are similar to the clamping elements l0 of the preceding embodiment. The sleeve portions 11, however, are in the form of separate tubular members positioned about the tie rods be` tween the pairs of clamping elements.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that, by employing the improvements of the present invention, the tubes are rigidly supported in proper spaced apart relation in a very simple and economical manner. The supporting means for the tubes will not interfere to any large eXtent with the flow of water through the chamber A. The heating unit may be very easily cleaned.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all mat-- ter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intend ed to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
